TECHNICAL FIELD

The present invention relates to an electronic cigarette, in particular,an aerosol electronic cigarette that doesn't contain tar but nicotine.

BACKGROUND ART

Today when “smoking is harmful to your health” has become a commonsense, there are one billion people smoking cigarettes, and this figureis still rising. On Mar. 1, 2003, the World Health Organization (WHO)issued the first international smoking ban—Framework Convention onTobacco Control. According to WHO's data, smoking causes 4,900,000deaths each year. Smoking causes serious respiratory system diseases andcancers, though it is a hard job to persuade the smokers to completelyquit smoking.

Nicotine is the effective ingredient of cigarette, which produces a lotof tar mist as the cigarette bums. The tar mist accesses the pulmonaryalveolus and is quickly absorbed into the blood. Nicotine thus acts onthe receptor of the central nervous system, bringing the euphoria likestimulant drugs to the smokers, who feel light in the head and on wingsas well.

Nicotine is a micromolecular alkaloid, which is basically harmless tohuman bodies with a small dosage. Plus, its half life period isextremely short in blood. Tar is the major harmful substance in tobacco.Tobacco tar comprises of several thousands of ingredients, dozens ofwhich are carcinogenic substances. It has now been proved that secondhand smoking is even more harmful to those who don't smoke.

To seek the cigarette substitutes that don't contain harmful tar butnicotine, many inventors have used the relatively pure nicotine tocreate such products as “Cigarette Patch”, “Nicotine Gargle”, “AerosolPacked in the High Pressure Tank with Propellant”, “Nicotine ChewingGum”, and “Nicotine Beverage”. These products are not as harmful as tar,but are absorbed very slowly. As a result, its peak concentration can'tbe effectively established in blood, and the smokers can't be satisfiedto the full. In addition, the smokers are deprived of the “smoking”habit. Therefore, the substituting products are not real cigarettesubstitutes or products helping to quit smoking.

The electronic cigarettes currently available on the market may resolvethe above-mentioned issue, though they are complicated in structure.Their cigarette bodies can be roughly divided into three sections, whichhave to be connected through via plugging or thread coupling before use.Also, their batteries have to be changed frequently, making itinconvenient for the users. What's worse, the electronic cigarettesdon't provide the ideal aerosol effects, and their atomizing efficiencyis not high.

SPECIFIC MODE FOR CARRYING OUT THE INVENTION

This invention is further described as follows on the basis of thedrawings.

As shown in FIG. 1-10, this utility model provides an aerosol electroniccigarette, which includes a battery assembly, an atomizer assembly and acigarette bottle assembly, and also includes a shell (a), which ishollow and integrally formed. The battery assembly connects with theatomizer assembly and both are located in the shell. The cigarettebottle assembly is located in one end of the shell, which is detachable.The cigarette bottle assembly fits with the atomizer assembly. The shellhas through-air-inlets (a1).

In this specific embodiment, the battery assembly includes the battery,and the operating indicator (1), electronic circuit board (4), andairflow sensor (5), which are connected with the battery. It alsoincludes a check valve (7). The signal output of the airflow sensor (5)is connected with the said electronic circuit board (4). The battery isa rechargeable battery (3), which may be either a rechargeable polymerlithium ion battery or a rechargeable lithium ion battery. The airflowsensor (5) may be alternatively a semiconductor force-sensitive chipcapacitance sensor or an inductance sensor. The rechargeable battery (3)has a flexibly connected charging plug (2). The blades (21) of thecharging plug (2) come out of the other end of the shell (a). Betweenthe charging plug (2) and rechargeable battery (3) is a spring (6),which lies against the body of the rechargeable battery (3) on one end,while its free end lies against the charging plug (2), forming aflexible structure, which buffers the charging plug (2) when plugged forcharging, thus protecting the rechargeable battery against any damage.Of course, the rechargeable battery (3) in this embodiment has acharging slot on it, which replaces the structure of charging plug (2)to perform the charging function and protect the rechargeable battery(3) against any damage. The operating indicator (1) is a LED. In thisembodiment, there are two LEDs. The electronic circuit board (4)includes an electronic switch circuit, which controls the electriccircuit according to the input signals, so that the rechargeable battery(3) electrifies the electric heating rod (82) inside the atomizer (8)and the LEDs as well.

As shown in FIGS. 1 and 2, the airflow sensor (5) has a silica gelcorrugated membrane (53), which connects with magnetic steel (54) with areed relay (52) on one of its ends. Both ends of the said reed relay(52) correspond to the relay electrodes (51) respectively.

As shown in FIG. 5-8, the atomizer assembly is an atomizer (8), whichincludes a porous component (81) and a heating rod (82). The body of theporous component (82) has a run-through atomizing chamber (811). Thediameter of the electric heating rod (82) is less than the diameter ofthe atomizing chamber (811). The electric heating rod (82) enters intothe atomizing chamber (811), and there is a clearance between theelectric heating rod (82) and interior wall of the atomizing chamber(811), which forms a negative pressure cavity (83). One end of the saidporous component (81) fits with the said cigarette bottle assembly. AsFIGS. 5, 7 and 8 show, the porous component (81) has a protuberance(812) on the other end, and the protuberance (812) fits with thecigarette bottle assembly. The protuberance (812) is a protruding halfsphere, on the side of which there is a run-through hole (813)connecting to the atomizing chamber (811). Of course, the protuberance(812) may also be a taper, rectangle or any other shape. The porouscomponent (81) is made of foamed nickel, stainless steel fiber felt,macromolecular polymer foam or foamed ceramics, providing the remarkablecapabilities in liquid absorption and diffusion, and the ability toabsorb the liquid stored in the cigarette bottle assembly.

As shown in FIG. 6, the electric heating rod (82) includes a cylinder(821). The heating wire (822) is wound on the wall of the cylinder(821). On the wall of both ends of the cylinder (821), there aremandrils (823) respectively, which lie against the interior wall of theatomizing chamber (811) of the porous component (81). There is anegative pressure cavity (83) between the electric heating rod andinterior wall of the atomizing chamber.

The heating wire is made of platinum wire, nickel-chromium alloy wire oriron-chromium alloy wire containing rare earth, or is flaked. Theelectric heating rod (82) may alternatively have on its peripheral wallthe heating layer made of electrically conductive ceramic PTC material,to replace the heating wire.

Of this embodiment, the battery assembly and atomizer assembly aremutually connected and then installed inside the integrally formed shell(a) to form a one-piece part. The rechargeable battery (3) may becharged without frequent change of battery. The user just needs to plugthe cigarette bottle assembly into the open end of the shell (a), foreasy use and very easy change.

As shown in 3 and 4, the cigarette bottle assembly includes a hollowcigarette holder shell (b), and a perforated component for liquidstorage (9) inside the shell (b). The perforated component for liquidstorage (9) is made of such materials as PLA fiber, terylene fiber ornylon fiber, which are suitable for liquid storage. Alternatively, itmay be plastic foam molding or column of multi-layer plates made throughplastic injection with polyvinyl chloride, ploypropylene andpolycarbonate. One end of the cigarette holder shell (b) plugs into theshell (a), and the outer peripheral surface of the cigarette holdershell (b) has an inward ventilating groove (b2). On one end surface ofthe cigarette holder shell (b), there is an air channel (b1) extendinginward. The air channel (b1) is located in the center on the surface ofone end of shell (b).

As shown in FIG. 1-9, one end of the porous component (81) lies againstone end surface of the said perforated component for liquid storage (9),and contacts the perforated component for liquid storage (9). It absorbsthe cigarette liquid from the perforated component for liquid storage(9). When the smoker smokes, the cavity of the cigarette holder shell(b) is in the negative pressure state. In the shell (b), one end of theairflow sensor (5) forms a normal pressure cavity, while the other endforms a negative pressure cavity. The air pressure difference betweenthe normal pressure cavity and negative pressure cavity or thehigh-speed airflow enables the magnetic steel (54) of the airflow sensor(5) to drive the reed relay(52) to contact the relay electrode (51). Asshown in FIG. 20, the electric circuit is electrified, and theelectronic switch circuit on the electronic circuit board (4) iselectrified. Thus, the rechargeable battery (3) starts to electrify theelectric heating rod (82) inside the atomizer (8), and at the same time,the LEDs, which are electrified by the rechargeable battery (3), emitlight. The air enters the normal pressure cavity through the air inlet(a1), passes the check valve (7) via the airflow passage in the airflowsensor (5), and flows to the negative pressure cavity (83) in theatomizer (8). Since the negative pressure cavity (83) provides thenegative pressure compared with the outside, the air flow sprays intoit, bringing the cigarette liquid from the porous component (81) tospray into the negative pressure cavity (83) in the form of fine drips.In the meantime, the electric heating rod (82) is electrified by therechargeable battery (3) under the control of electronic circuit board(4), to heat the fine drips for atomization. After atomization, thebig-diameter fine drips are re-absorbed by the porous component (81)under the action of vortex, while the small-diameter fine drips aresuspended in the airflow to form gasoloid, which is discharged throughthe negative pressure cavity (83) and run-through hole (813), flows intothe cigarette holder shell (b) of the cigarette bottle assembly, and isabsorbed by the air channel (b1). When the gasoloid enters the cigaretteholder shell (b), multiple small liquid drips are condensed into biggerones, which fall into the clearance between the cigarette holder shell(b) and air channel (b1) without being absorbed by the air channel (b1).The perforated component for liquid storage (9) of the cigarette bottleassembly and the porous component (81) of the atomizer (8) contact eachother to achieve the capillary impregnation for liquid supply.

The unit and its connecting structure of this invention may also beloaded with drugs for delivery to the lung.

As shown in FIGS. 22, 23 and 24, the electronic cigarette (5) is held ina charging device. The charging device includes a case (1), whichcontains an auxiliary charging storage battery (2) inside it, and holdsthe electronic cigarette (5) and the charger (3) for the rechargeablebattery embedded in the electronic cigarette (5), as well as the powersupply circuit. The power inputs of the auxiliary charging storagebattery (2) and charger (3) are connected with the power supplyrespectively. The charger (3) in this embodiment is a constant voltage &current charger. It may be a GY5210 charger, or any other constantvoltage & current charger. The case (1) has a spare liquid supply bottle(4) in it. The power output of the auxiliary charging storage battery(2) is connected with the power input of the charger (3). The poweroutput of the charger (3) is a charging slot (31), which fits with thecharging plug of the rechargeable battery inside the electroniccigarette, or a charging plug, which fits with the charging slot of therechargeable battery.

As shown in FIGS. 23 and 24, on the body of the shell (1), there is apair of slide ways (12) corresponding to the position of the electroniccigarette, and on the slide ways, there is a slide cover (11).

In the second preferred embodiment of this utility model, a restrictioncomponent (10), which is detachable, is set on one end of the saidporous component (81). There is a restriction hole (101) on the body ofthe restriction component (10). The restriction hole (101) correspondsto the atomizing chamber (811). The pore diameter of the restrictionhole is less than the inner diameter of the atomizing chamber (811) tothe extent that the size of the restriction component (10) installed onthe porous component (81) varies, for the purpose of airflow capacitycontrol. On the basis of different applications, the restrictioncomponent of different sizes and pore diameters may be used.

In the third preferred embodiment of this utility model, as shown in 11and 12, on the outer peripheral wall of the cigarette shell (b), thereis a protruding rib (b2) that is evenly partitioned. The perforatedcomponent for liquid storage (9) enters the cigarette holder shell (b)and lies against the protruding rib (b2). Thus, there appears aclearance between the outer peripheral surface of the perforatedcomponent for liquid storage (9) and the interior wall of the shell (b).The clearance is for connection the shell (a) and cigarette holder shell(b). When the user smokes, the air channel (b1) absorbs the air to causeairflow inside the shell (a), thus triggering the airflow sensor (5) andeventually starting the electronic cigarette. Also, the atomizer (8)works to atomize the cigarette liquid and produce gas flow, which entersthe cigarette holder shell (b).

In the fourth preferred embodiment of this utility model, as shown inFIGS. 13, 14, 15 and 16, on one end of the cylinder (821), there is afixed plate (84), whose outer peripheral wall has partitioned supports(841). The outer ends of the supports (841) lie against the interiorwall of the shell (a), thus suspending the cylinder (821), which isconnected with the fixed plate (84), in the cavity of the shell (a). Onthe surface of the fixed plate (84), there is a mandril (842), whosefront end lies against one end of the porous component (81), so that thefixed plate (84) is separated from the atomizing chamber (811) of theporous component (81). As a result, the run-through hole on one end ofthe atomizing chamber (811) won't be blocked, and the mist generated inthe atomizing chamber (811) can be dispersed. One end of the porouscomponent (81) has two protuberances (812) at the outlet of theatomizing chamber (811). Between the two protuberances (812) is aclearance. The two protuberances (812) lie against the perforatedcomponent for liquid storage (9).

In the fifth preferred embodiment of this utility model, as shown inFIGS. 17 and 18, the atomizer assembly is an atomizer (8), whichincludes a frame (82), the porous component (81) set on the frame (82),and the heating wire (83) wound on the porous component (81). The frame(82) has a run-through hole (821) on it. The porous component (81) iswound with heating wire (83) in the part that is on the side in theaxial direction of the run-through hole (821). One end of the porouscomponent (81) fits with the cigarette bottle assembly. The porouscomponent (81) is made of foamed nickel, stainless steel fiber felt,macromolecular polymer foam or foamed ceramics.

In the sixth preferred embodiment of this utility model, as shown inFIG. 19, the airflow sensor (5) has a silica gel corrugated membrane(53), which connects with magnetic steel (54) with a Hall element (52),or a magneto-diode or a magneto-triode on one of its ends.
